BACKGROUND

1. Field

The following description relates to a hermetic type compressor, and inparticular, to a hermetic type compressor in which an electric componentbracket installed on an outer surface of a hermetic container to beconnected to an electric component cover may be easily changed in designand replaced with a new electric component bracket.

2. Description of the Related Art

In general, a hermetic type compressor employed by a cooling apparatusof an air conditioner or a refrigerator to compress a refrigerantincludes a compression unit and a drive unit provided in a hermeticcontainer. The compression unit performs compression of the refrigerant,and the drive unit provides driving force to compress the refrigerant.

The drive unit generally may include a motor, and connection terminalsmay be installed on the hermetic container so as to apply power to thedrive unit.

One end of each connection terminal may be exposed to the outside of thehermetic container, and the other end of each connection terminal may beconnected to the driving unit within the hermetic container. Electriccomponents relating to drive of the drive unit, such as an overloadprotector and a relay, may be connected to the ends of the connectionterminals exposed to the outside of the hermetic container.

Such electric components may be protected by an electric componentcover, and an electric component bracket to be connected to the electriccomponent cover may be provided on the outer surface of the hermeticcontainer around the connection terminals.

In a conventional hermetic type container, the electric componentbracket is made of a thin metal sheet and is fixed to the outer surfaceof the hermetic container by welding. A hole to expose the connectionterminals is formed through the center of the electric componentbracket, and fastening structures to be fastened to the electriccomponent cover are provided at the edge of the electric componentbracket.

Therefore, the electric components are connected to the connectionterminals under the condition that the electric component bracket iswelded onto the outer surface of the hermetic container. Under thisstate, the electric component cover is connected to the electriccomponent bracket so as to cover the electric components.

However, in the conventional hermetic type container, in which theelectric component bracket is fixed to the outer surface of the hermeticcontainer by welding, the electric component bracket may be difficult toreplace, thereby causing an inconvenience.

In the conventional hermetic type container, if the electric componentbracket is partially damaged or is defective, replacement of only theelectric component bracket is difficult, and thus it may be necessary toreplace the overall hermetic container including the electric componentbracket with a new one.

Further, the number of the electric components may be changed or theelectric components may be changed into other kinds according to thespecifications of the hermetic type compressor. When the number or kindsof the electric components are changed, a type of the electric componentcover to cover the changed electric components needs to be changed andthe electric component bracket also needs to be replaced with a new typecorresponding to the changed type of the electric component cover.Further, the type of the electric component cover may be changedaccording to an internal structure of a cooling apparatus in which thehermetic type compressor is installed even if the same electriccomponents are covered with the electric component cover, and in thiscase, the electric component bracket needs to be replaced with a newtype corresponding to the changed type of the electric component cover.That is, various types of electric component brackets are requiredaccording to user environments.

However, since the replacement of the electric component bracket fixedto the hermetic container with a different type of electric componentbracket is difficult, if a new electric component bracket having adifferent specification is required in a conventional hermetic typecompressor manufacturing line, manufacturing equipment to install thenew electric component bracket on the outer surface of the hermeticcontainer is prepared.

DETAILED DESCRIPTION

The following detailed description is provided to assist the reader ingaining a comprehensive understanding of the methods, apparatuses,and/or systems described herein. Accordingly, various changes,modifications, and equivalents of the systems, apparatuses, and/ormethods described herein will be suggested to those of ordinary skill inthe art. The progression of processing steps and/or operations describedis an example; however, the sequence of steps and/or operations is notlimited to that set forth herein and may be changed as is known in theart, with the exception of steps and/or operations necessarily occurringin a certain order. Also, descriptions of well-known functions andconstructions may be omitted for increased clarity and conciseness.

A hermetic type compressor may be employed by a cooling apparatus of arefrigerator or an air conditioner to compress a refrigerant, andinclude a hermetic container forming an external appearance of thehermetic type compressor.

As shown in the example of FIG. 1, a compression unit 100 to performcompression of the refrigerant and a drive unit 200 to provide drivingforce to compress the refrigerant may be installed in the hermeticcontainer 1. The drive unit 200 includes a motor including a stator 210and a rotor 220, and a rotary shaft 230 to transmit the driving force ofthe drive unit 200 to the compression unit 100 is pressed into the rotor200.

The compression unit 100 includes a piston 120 connected to an eccentricpart 231 formed at one end of the rotary shaft 230 through a connectingrod 110 and rectilinearly reciprocating within a compression chamber.

When the rotor 220 is rotated through electrical interaction between thestator 210 and the rotor 220 by applying power to the stator 210 throughthe above structure, the rotary shaft 230 pressed into the rotor 220 isrotated together with the rotation of the rotor 220, and the piston 120connected to the eccentric part 231 of the rotary shaft 230 through theconnecting rod 110 rectilinearly reciprocates within the compressionchamber, achieving compression of the refrigerant.

The hermetic type compressor may generally refer to a reciprocatingcompressor including a compression unit having a connecting rod and apiston. Hermetic type compressors may generally include a rotarycompressor, each of which includes a drive unit driven by power,regardless of types of compression units, and a compression unit toperform compression of a refrigerant through driving of the drive unit.

As shown in the examples of FIGS. 1 and 2, a hermetic container 1 isformed by connecting an upper container 11 and a lower container 10 toeach other. Connection terminals 31 for connection with electriccomponents 20 relating to driving of the drive unit 200, i.e., applyingof power to the drive unit 200, are installed at one side of the lowercontainer 10. The connection terminals 31 are installed on the lowercontainer 10 through a terminal housing 30. The terminal housing 30passes through one side of the lower container 10, and the connectionterminals 31 pass through the terminal housing 30 such that one end ofeach connection terminal 31 is exposed to the outside of the hermeticcontainer 1 and the other end of each connection terminal 31 isconnected to the drive unit 200 in the hermetic container 1. Electriccomponents 20 relating to driving of the drive unit 200, including anoverload protector 21 and a relay 22 are connected to the ends of theconnection terminals 31 exposed to the outside of the hermetic container1. Various kinds of the overload protector 21 and the relay 22 may beused, and the electric components 20 may include other electronic partsrelating to driving of the drive unit 200 in addition to the overloadprotector 21 and the relay 22. The overload protector 21 and the relay22 are illustrated simply to show examples of electric componentsrelating to the driving of the drive unit 200.

The electric components 20 located at the outside of the hermeticcontainer 1 are covered with an electric component cover 40. An electriccomponent bracket 50 to be connected to the electric component cover 40is provided on the outer surface of the hermetic container 1 around theconnection terminals 31.

The hermetic type compressor is configured such that the electriccomponent bracket 50 may be replaced with a new one according to userenvironments.

That is, with reference to FIGS. 2 to 7, for example, in a hermetic typecompressor, bracket fixing members 60 are provided on the outer surfaceof the lower container 10 around the connection terminals 31 such thatthe electric component bracket 50 is detachably connected to the bracketfixing members 60. First fastening units 61 are provided on the bracketfixing members 60, and second fastening units 51, which may bedetachably connected to the first fastening units 61, are provided onthe electric component bracket 50.

Therefore, in the hermetic type compressor, if replacement of theelectric component bracket 50 is required according to userenvironments, such as if the type of the electric component cover 40 ischanged as the number or the kinds of the electric components 20 arechanged, the design of the electric component cover 40 is changed, orthe electric component bracket 50 is damaged, the electric componentbracket 50 may be simply replaced with a new one.

The bracket fixing members 60 may be formed in the shape of a smallmetal piece, and regions of the bracket fixing members 60 mayrespectively form the first fastening units 61. The first fastening unit61 of each bracket fixing member 60 includes a protrusion part 61 aprotruded outwardly from the outer surface of the hermetic container 1when each bracket fixing member 60 is installed on the outer surface ofthe hermetic container, and a hanging part 61 b having a cross-sectionalarea greater than that of the protrusion part 61 a and provided at oneend of the protrusion part 61 a. The other end of the protrusion part 61a opposite to the hanging part 61 b forms a fixing surface 62 welded tothe outer surface of the lower container 10 to fix each bracket fixingmember 60.

The electric component bracket 50 may be formed in the shape of a thinmetal sheet. An exposure hole 52 to expose the connection terminals 31and the terminal housing 30 is formed through the center of the electriccomponent bracket 50. In this example, each second fastening unit 51 isprovided in the shape of a hole formed through the electric componentbracket 50 around the exposure hole 52.

Each second fastening unit 51 includes a hanging part pass hole 51 aconfigured to pass the hanging part 61 b of the first fastening unit 61,and a protrusion part fitting hole 51 b formed at the top of the hangingpart pass hole 51 a and having a width corresponding to the width of theprotrusion part 61 a such that the protrusion part 61 a of the firstfastening unit 61 may be fitted into the protrusion part fitting hole 51b. The hanging part pass hole 51 a and the protrusion part fitting hole51 b are formed so as to be communicated with each other. A length ofthe protrusion part fitting hole 51 b in the vertical direction may beequal to or be greater than by a designated length a thickness of theprotrusion part 61 a in the vertical direction.

Therefore, when the electric component bracket 50 is fastened to thebracket fixing members 60 under the condition that the bracket fixingmembers 60 are welded onto the hermetic container 1, the electriccomponent bracket 50 may move toward the hermetic container 1 under thecondition that the electric component bracket 50 is located in front ofthe bracket fixing members 60 so as to cause the hanging parts 61 b ofthe first fastening units 61 and the hanging part pass holes 51 a of thesecond fastening units 51 to coincide with each other, as shown in FIGS.4 and 5, allowing the hanging parts 61 b of the first fastening units 61to pass through the hanging part pass holes 51 a of the second fasteningunits 51. Thereafter, the electric component bracket 50 is pulleddownwards so as to fit the protrusion parts 61 a of the first fasteningunits 61 into the protrusion part fitting holes 51 b of the secondfastening units 51, as shown in FIGS. 6 and 7, for example. The electriccomponent bracket 50 may be simply fastened to the bracket fixingmembers 60 by hanging the hanging parts 61 b of the first fasteningunits 61 onto the protrusion part fitting holes 51 b of the secondfastening units 51.

When the electric component bracket 50 is pulled forwardly from thehermetic container 1, under the condition that the electric componentbracket 50 is lifted up such that the hanging parts 61 b of the firstfastening units 61 and the hanging part pass holes 51 a of the secondfastening units 51 coincide with each other, so as to allow the hangingparts 61 b to come out of the hanging part pass holes 51 a, the electriccomponent bracket 50 is separated again from the bracket fixing members60. Therefore, the electric component bracket 50 may maintain a state ofbeing firmly fixed to the bracket fixing members 60 unless the hangingparts 61 b of the first fastening units 61 come out of the hanging partpass holes 51 a of the second fastening units 51 by lifting up theelectric component bracket 50 fastened to the bracket fixing members 60.

To stably maintain the fastened state of the electric component bracket50 onto the outer surface of the hermetic container 1, at least twobracket fixing members 60 may be provided around the connectionterminals 31. In one example, three bracket fixing members 60 aredisposed in a triangular shape around the terminal housing 30,supporting the electric component bracket 50 at three points. However,any suitable number of bracket fixing members 60 may be used.

Further, to prevent or limit movement of the electric component bracket50 fastened to the bracket fixing members 60, a protruding length of theprotrusion parts 61 a of the first fastening units 61 may be about equalto a thickness of the electric component bracket 50.

FIG. 8 illustrates an example in which the electric component cover 40is separated from the electric component bracket 50 fixed to the outersurface of the hermetic container 1 through the bracket fixing members60.

The electric component cover 40 may be provided in the shape of a boxhaving one surface opened toward the hermetic container 1. The electriccomponent cover 40 may be an injection-molded product made of plastic soas to be elastically deformable, and have a small wall thickness.

The electric component cover 40 may be detachably connected to theelectric component bracket 50. For this purpose, third fastening units53 are provided on the electric component bracket 50, and fourthfastening units 41 to which the third fastening units 53 may bedetachably connected are provided on the electric component cover 40.

The third fastening units 53 are formed at the edge of the electriccomponent bracket 50 so as not to interfere with the first fasteningunits 61 of the bracket fixing members 60. Each third fastening unit 53includes a protrusion piece 53 a protruded toward the electric componentcover 40, and a hanging hole 53 b formed through the protrusion piece 53a.

Further, each fourth fastening unit 41 includes a support piece 41 aprovided at the inside of the side wall of the electric component cover40 and separated from the side wall of the electric component cover 40so as to be supported by the inner surface of the protrusion piece 53 a,and a hanging protrusion 41 b protruded from the outer surface of thesupport piece 41 a so as to be fitted into the hanging hole 53 b. Thesupport piece 41 a may have a small thickness so as to be elasticallydeformed to fit into the hanging hole 53 b.

Therefore, the electric component bracket 50 and the electric componentcover 40 may be detachably fastened to each other under the conditionthat the electric component bracket 50 is fixed to the outer surface ofthe lower container 10 through the bracket fixing members 60. Forexample, the electric component cover 40 may be pressed toward thehermetic container 1 while contacting the front surface of the electriccomponent bracket 50 so as to fit the hanging protrusions 41 b of thefourth fastening units 41 into the hanging holes 53 b of the thirdfastening units 53.

To separate the electric component cover 40 from the electric componentbracket 50, external force may be applied to both side walls of theelectric component cover 40 so as to cause both side walls to get closerto each other. Then, the support pieces 41 a of the fourth fasteningunits 41 may be elastically deformed and thus the hanging protrusions 41b may become separated from the hanging holes 53 b of the thirdfastening units 53. By pulling the electric component cover 40 forwardlyfrom the hermetic container 1, the electric component cover 40 isseparated from the electric component bracket 50.

As described above, in the hermetic type compressor, the electriccomponent bracket 50 may be detachably connected to the outer surface ofthe hermetic container 1 through the first fastening units 61 of thebracket fixing members 60 connected to the outer surface of the hermeticcontainer 1 and the second fastening units 51 provided on the electriccomponent bracket 50. Thus, if the electric component bracket 50 isdefective or damaged, there may be no need to replace the whole of thelower container 10, as only the electric component bracket 50 may bereplaced.

Further, in the hermetic type compressor, as far as the first fasteningunits 61 and the second fastening units 51 may be detachably connectedto each other, the electric component bracket 50 may be replaced withany one of various types of electric component brackets in which otherstructures except for the second fastening units 51 are different.Therefore, if a change in design of the electric component bracket 50 isrequired, for example, in accordance with a change in design of theelectric component cover 40, or a change in specification of theelectric component bracket 50, the electric component bracket 50 may besimply replaced with various types of electric component brackets.

Further, in the hermetic type compressor, the electric component bracket50 may be fastened to the outer surface of the hermetic container 1 in asimple fit manner. Thus, although a hermetic type compressormanufacturer may manufacture a hermetic type compressor provided withonly the bracket fixing members 60, without the electric componentbracket 50, and may provide the hermetic type compressor to a user, theuser may easily prepare the electric component bracket 50 detachablyconnected to the bracket fixing members 50 of the supplied hermetic typecompressor. Otherwise, although a manufacturer simultaneously providesvarious kinds of electric component brackets having different types to auser, the user may select an electric component bracket desired by theuser out of the various electric component brackets as long as theelectric component brackets have the same structure of second fasteningunits.

The bracket fixing members and the second fastening units provided todetachably connect the electric component bracket to the bracket fixingmembers may be modified into various types differing from the type.

That is, as shown in FIGS. 9 to 11, which illustrate other examples, apair of bracket fixing members 60′ is disposed around connectionterminals 31 such that the bracket fixing members 60′ are separated fromeach other by a designated interval in the circumferential direction.However, at least three bracket fixing members 60′ may be provided asfar as the bracket fixing members 60′ are disposed around the connectionterminals 31 such that the bracket fixing members 60′ are separated fromeach other by a designated interval in the circumferential direction.

A pair of second fastening units 51′ is also provided on an electriccomponent bracket 50′ so as to correspond to the number of the bracketfixing members 60′. When the electric component bracket 50′ is rotatedunder the condition that the second fastening units 51′ enter an areabetween the bracket fixing members 60′, the second fastening units 51′are fastened with first fastening units 61′ provided on the bracketfixing members 60′.

The second fastening units 51′ are provided on the rear surface of theelectric component bracket 50′ around an exposure hole 52 such that thesecond fastening units 51′ are separated from each other by a designatedinterval in the circumferential direction. In this example, each secondfastening unit 51′ includes an extension part 51 a′ extended backwardlyfrom the rear surface of the electric component bracket 50′, and afitting part 51 b′ bent from the extension part 51 a′ in the radialdirection so as to be parallel with the electric component bracket 50′.

Further, each first fastening unit 61′ includes a fitting groove intowhich the fitting part 51′ of the second fastening unit 51′ may befitted while sliding in the circumferential direction when the electriccomponent bracket 50′ is rotated. That is, the bracket fixing member 60′is formed to have an arc-shaped cross section, i.e., about an L-shapedcross section and is welded to the outer surface of the hermeticcontainer 10, and the first fastening unit 61′ is an arc-shaped fittinggroove formed between the bracket fixing member 60′ and the outersurface of the hermetic container 10.

Therefore, in this example, to connect the electric component bracket50′ to the hermetic container 10, the fitting parts 51 b′ of the secondfastening units 51′ enter the area between the bracket fixing members60′ under the condition that the electric component bracket 50′ isrotated by an angle of 90 degrees, as shown in FIG. 10, for example.Thereafter, when the electric component bracket 50′ is rotated by anangle of 90 degrees in the clockwise direction so as to stand erect, asshown in FIG. 11, the fitting parts 51 b′ of the second fastening units51′ are fitted into the first fastening units 61′ and then the electriccomponent bracket 50′ may be simply connected to the outer surface ofthe hermetic container 10.

To prevent or limit movement of the electric component bracket 50′ underthe condition that the first fastening units 61′ and the secondfastening units 51′ are fastened to each other, the fitting parts 51 b′and the first fastening units 61′ may be connected to each other in aninterference fit manner. Further, to complete fastening of the firstfastening units 61′ and the second fastening units 51′ to each otherunder the erect standing state of the electric component bracket 50′, arestriction protrusion 63 to restrict sliding of the fitting part 51 b′is provided at one end of each first fastening unit 61′.

In order to separate the electric component bracket 50′ fixed to theouter surface of the hermetic container 10 from the hermetic container10, the electric component bracket 50′ is rotated from the state of FIG.11 in the counterclockwise direction so as to be converted into thestate of FIG. 10. The fitting parts 51 b′ may come out of the firstfastening units 61′, and then the electric component bracket 50′ maysimply be separated from the hermetic container 10.

Other parts in this example, except for the first and second fasteningunits 61′ and 51, may be the same as those in the examples of FIGS. 1 to8, and an attachment and detachment structure between the electriccomponent bracket 50′ and the electric component cover 40 in thisexample is substantially similar to that described above.

As is apparent from the above description, a hermetic type compressormay enable an electric component bracket for connection with an electriccomponent cover to be detachably connected to the outer surface of ahermetic container through bracket fixing members.

Therefore, if replacement of the electric component bracket is requiredaccording to user environments, such as if the type of the electriccomponent cover is changed as the number or the kinds of electriccomponents are changed, if the design of the electric component cover ischanged, or if the electric component bracket is damaged, the electriccomponent bracket may be simply replaced with a new one, and designchange of the electric component bracket may be more easily performed.

A number of examples have been described above. Nevertheless, it will beunderstood that various modifications may be made. For example, suitableresults may be achieved if the described techniques are performed in adifferent order and/or if components in a described system,architecture, device, or circuit are combined in a different mannerand/or replaced or supplemented by other components or theirequivalents.
